Effect of PGR's on Growth, Seed Yield and Quality of Coriander

A field experiment entitled "Effect of growth regulators on growth, seed yield and quality of Coriander (Coriandrum sativum L.) cv. Sudha" was conducted during Rabi 2013-2014 at Horticultural College and Research Institute Farm, Dr. Y.S.R. Horticultural University, Anantharajupet, Y.S.R. district of Andhra Pradesh. The experiment consists of 6 levels of plant growth regulators viz., GA3 (50 and 75 ppm), NAA (10 and 25ppm) and Cycocel (100 and 250 ppm) as presoaking, foliar spray at 30 and 60 DAS. An absolute control was also maintained. The experiment consists of 7 treatments replicated thrice in a randomized block design. The results indicated that application of 75 ppm GA3 resulted in maximum plant height (78.09 cm). However, maximum number of primary branches per plant (7.13), number of secondary branches per plant (16.13), number of umbels per plant (28), number of umbellets per umbel (6.33), number of seeds per umbel (34.73), seed yield per plant (9.02 g) and seed yield per hectare (18.46 q) was maximum with 250 ppm Cycocel. However GA375 ppm followed by GA350 ppm recorded minimum number days to 50 per cent flowering (40.33) and maturity (85.00).
